[state:modified] store unrendered_database and unrendered_schema on source definition for state:modified comparisons

[MichelleArk]

Resolves #9573

Problem

source definitions in schema yaml files often include jinja in the database and schema properties.

However, this makes them sensitive to environment in that the env var/var/jinja resolution may change between runs without the actual source changing, leading to false positives.

Solution

Start persisting unrendered_database and unrendered_schema during source parsing, and do comparison on unrendered values during state:modified, behind state_modified_compare_more_unrendered behaviour flag.

Sorry about the messy commit history, I think it's a GH issue from when the base was changed from #10487 to main. The changed files and contents all look correct though.
